[{"name":"miocene-temperature-portal-2","title":"Miocene temperature portal","summary":"This data portal serves as a resource for investigators interested in the study of Miocene climate, about 23 to 5 million years ago. It collates a list of key information about published Miocene ocean temperature records to enable researchers to rapidly locate and evaluate datasets relevant to the study of Miocene climate change.\r\n\r\nThe resource provides the metadata for study sites, a map of the location of these sites, references to papers describing the datasets, and links to where each dataset is archived.\r\n\r\nThe resource also contains a user interface that allows researchers to add information about their new published datasets to the inventory such that it will continue to provide an up to date listing of existing Miocene temperature proxy records.","citations":"\r\n  Badger MPS, Lear CH, Pancost RD, et al.
